Extensive Definition

Pyranose is a collective term for carbohydrates which have a chemical structure that includes a six-membered ring consisting of five carbons and one oxygen. The pyranose ring is formed by the reaction of the C-5 alcohol group of a sugar with its C-1 aldehyde forming an intramolecular hemiacetal. The name derives from its similarity to the oxygen heterocycle pyran.
